To all whom it may concern Be it known that I, IRA H. SPENopR, a citizen of the United States, and a resident of Hartford, in the county of Hartford and I State of Connecticut, (whose POSt-OfllCG address is Hartford, Connecticut,) have 1nvented certain new and useful Improvef ments in Cleaning Apparatus and Dust-- Separators, of which the following is a full, clear, and exact description, whereby any. one skilled in the art may make and use:

the same.

The invention relates to cleaning apparatus and dust separators, and more particularly to a device in which the cleaning is effected by a suction and the separation of the particles carried by the moving fluid from said fluid is effect-ed by vthe centrifugal action of the suction apparatus.

The objects of the invention are to provide a simple and extremely eflicient suction inducing apparatus, having inherent traneous matter from a given fluid which is drawn in by the suction.

A further object is to provide positive means for maintaining the desired separation of the extraneous material. 7

A still further object is to provide a suction apparatus which will give free passage of all material drawn into it with positive retarding devices for absolutely purifying the fluid at the exhaust side of the device. it Referring to the drawings: Figure 1 is a partial central sectional view of the apparatus. Fig. 2 is-a cross sectional view on the line X X of Fig. 1 showing attached cleaning tools. Fig. 3 is a central sectional view of the exhaust chamber and appurtenant retarding screens. Fig. 4 is a cross sectional view through Fig. 3 on the line Y Y of said figure. Fig. 5 is a detail perspective view of one of the collecting receptacles. Fig. 6 is a detail plan view of the inlet tube or casing.

One of the particular objects of the present invention lies in the method of separating all matter picked up by the cleaning tools from the fluid passed throu ,h the apparatus, and further, to provi e efficient cleansing devices appurtenant to the exhaust side of the mechanism.

Referring to the drawings, numeral 1 denotes a casing, within which there is arranged a series of disks or plates 2, pro- 8. The plates 7 are secured to hubs 9 mount-.

ed upon and rotatable with the main shaft 5. This main shaft 5 is mounted in anti-friction bearings 1011 arranged in headers 1213 which form the ends of the casing 1. A. thrust bearing 14 is provided at one end of the shaft 5 to maintain the impellers 1n predetermined and proper running aline ment with reference tothe deflector plates.

For convenience the casing 1 is provided with a series of covers 15 which overlie openings in said casing and give access to each of the impeller chambers. This provides a ready means of ingress to either of the chambers. Adjacent to the inlet side of the casing 1 is a transversely disposed receiving casing 16, provided with a removable tray or box of tubular form 17. The

tubular casing 16 arranged transversely of the main casing 1 extends beyond it and has rising from one end a tubular inlet pipe 18 which is preferably of elliptical form, giving an area many times greater than the inlet tube or dome 19. To this inlet tube 19 may be attached any desired number of cleaning tubes 20, which may be attached to any desired form of cleaning tool, one form of which is illustrated at 21.

By having the inlet tube or pipe 18 of larger area than the inlet pipe 20, the fluid will move more slowly down through said tube when the suction is induced by the impellers. This slow movement of the air at the entering side of the suction apparatus will permit all heavier particles of materialv carried by the incoming fluid to drop into the receptacle 17.

The inlet tube or ipe 18 is preferably located at one side of the impeller casing 1, and owing to the transverse intersection of the casing 16 with the casing 1 the fluid must take a short turn when passing from the inlet tube 18 to the interior of the impeller casing. Thus the fluid is sucked about a sharp turn 22 and will deposit in the receptacle 17 all of the heavier matter carried in suspension. The fluid after passing the sharp turn 22 passes into the first impeller chamber 23 and from there is suc- 27 and being smallerin diameter than casing 1 provides an annular chamber-'28. At one side of said chamber 28 and connecting therewith is a chamber 29, within which is located a receiver 30'similar in form and arrangement to the receiver 17 heretofore described.

Appurtenant to the casing 1 is an exhaust casing 31 which communicates with the interior of the impeller casing 1 through a passage 32 and the central opening 27 of the plate or header 26. The exhaust casing 31 is provided with an outlet 33 and handholes 34-35 to give, access for the purposes of inspection, cleaning and adjustment. The hand-hold 34, is arranged adjacent to the upper portion of the exhaust casing and gives access above the tubular screens While the hand-hold 35,.is arranged adjacent to the bottom of the exhaust casing and gives access below the tubular screens hereinafter described. These hand-holds are of course covered with suitable removable caps or doors which may be locked in any desired Arranged at the topor dome of the exhaust casing are a number of supports 36, to whigh are secured resilient supporting members 37, which at their opposite ends are connected to tubular screens 38. These tubular screens at their lower end are securedinabase plate 39 secured at the bottom of the exhaust casing and open into the chamber or air passage 32 communicating with the interior of the impeller casing. The tubular screens may be arranged in any desired number or juxtaposition, and it will be noted that by using a plurality of tubes within the exhaust chamber, the screening area is very materially increased.

The impregnated fluid entering the inlet tube or pipe, first. deposits itsheavier particles of material in the receptacle 17 as it passes the sharp turn 22, then as it is drawn into the various impeller chambers, it is finally thrown out to the impeller 24 which is located in the perforated cylindrical chamber 25. Its movement through the im- 'peller casing toward the outlet chamber is very slow, while its rotary or swirling movement induced by the last impeller 24 is very 7 rapid. In fact, the fluid will be caused to revolve many thousand times inside the perforated cylindrical chamber before it finally reaches the outlet opening 27. During this high rotary movement practically all of the impregnating material will be thrown off significant and finest particles carried in suspension will be borne through said opening and up into the tubular screens 38; These tubular screens or retarders 38 are of'such a texture as to prevent the passage of even the finest particles to the exhaust chamber and exhaust outlet 33. Whatever accumulation of fine dust there may bein the tubes 38 may beshaken down over deflector plates 41 and 42 through the perforated cylindrical chamber into the receptacle 30 Obviously, the exact details and arrangements possible might be varied to suit the exigencies of any particular case without departing from the spirit or intent of the invention.

Attention is particularly called to the advantages in providing, first for the removal of heavy particles borne by the fluid, the free passage of said fluid through the suction inducing apparatus, the separation by centrifugal action of all of the appreciable impregnating material by a rapid swirling action, and the perfect cleansing provided by a positive separator having an extremely lar e area.

y improved separating apparatus is the fluid or how completely it maybe impregnated with extraneous matter, there will be no clogging of the positive separator or retarding screens, such as will'make the apparatus ineflicient in its work. In fact, the cleaningtools may be of a proper design for scrubbing and may be used in connection with water. Owing to the large volume of air taken in through said tool the muddy or dirty water may be instantly picked up and the surface being scrubbed, will be almost instantly dried. This muddy water will be thrown off before it has clogged the final collecting screen or retarder.

The device herein shown and described, while similar to a device shown in co-pending application for suction cleaner and dust separator Serial No. 403,318, filed Nov.
